  • Cementitious composition
    Patent number: 5501819
    Abstract: A cementitious composition containing metal-coated fibres especially metal-coated carbon fibres in an amount of 0.1 up to 5% by weight relative to the weight of the cement component of the composition. The composition can be used as a conductive layer in a cathodically protected reinforced concrete.
    Type: Grant
    Filed: October 7, 1994
    Date of Patent: March 26, 1996
    Assignee: ICI Americas Inc.
    Inventors: Luc B. J. Westhof, Ibrahim Turhan, George G. Tessier, Frans L. J. De Peuter
  • Cathodic protection system and a coating and coating composition therefor
    Patent number: 5431795
    Abstract: Cathodic protection system for the cathodic protection of a reinforced concrete structure, which system comprises a concrete structure containing steel reinforcement bars and an electrically conductive coating bonded to an external surface and in electrical contact with the structure, and wherein said electrically conductive coating is a non-cementitious coating comprising a matrix of an organic polymer containing electrical conductivity-providing particles of carbon coated with a conductive metal of a type possessing a natural passive oxide film which is itself electrically conductive, and an alkaline buffer material or combination of materials for inhibiting or preventing the build up of acidity in the coating when the cathodic protection system is in operation.
    Type: Grant

  • Modified cementitious composition
    Patent number: 5254228
    Abstract: A cementitious composition which contains a base which preferably has a solubility which is greater than that-of calcium hydroxide. The amount of this base is such as to provide 0.1 to 2% by-weight of hydroxide relative to the weight of the cementitious composition. The cementitious composition may be a polymer modified mortar which is used as the anode overlay in a cathodically protected reinforced concrete.
